According to the weight of my coach and the Michelin Tire Chart (with a little self conversion) I should be able to use 75# of air all around, however the Chart only goes down to 85#, which is more weight carrying capacity they I have. When I questioned Michelin all they would say was that they had never tested this tire below 85#. I know I probably have more tire than necessary but when I got rid of the original 80 series tire and went to a 70 series to get a little more hefty tire this was what I ended up with.
Now the question: I run 85# in normal summer driving but going into a mountain campground in Colorado for a few days with temperatures hitting 28-34 degrees in early mornings my Pressure Pro will indicate tire pressures 8-10 lbs lower than normal. By noon time even in the cooler temperatures the tire pressures will be back up to normal with the sun shinning. Should I be getting my air hose out and running the engine in the CG to just air the tires back up to 85 then stop in an hour or so after getting down to warmer temperatures and bleed back down to where they should be? Seems like a lot of work when I have excess tire carrying capacity anyway.
Thoughts from the experts?
